There is no evidence for hydrfde shift in the reaction of WhoIs 1 and 2 with dchbrocarbene. Accordingly, the intermedate cannot be a free catbocation. It is suggested that the pmducts are formed through a cotnttinatfon of SNi and direct dispketnent reactfons in which tfght bn pairs are involved. J
## Abstract Interaction of tropone and phenylmagnesium bromide yields 2βphenylβ2,7βdihydrotropone (II). This compound is in thermal equilibrium with 2βphenylβ6,7βdihydrotropone (III) in a 1: 4 ratio. The reaction of 2βchlorotropone with isopropylmagnesium bromide yields a mixture of chloroisopropy
